This is the Comfort Oasis ultrasonic nebulizer from Shin-ei Industry, a medical device manufacturer. I purchased it in March 2024 for post-operative care for my dog's tracheal collapse, as recommended by my veterinarian. (Receipt included in the photos) Only the main unit and hose have been used. The hose has not come into contact with the dog. The hose has been cleaned, air-dried, and dried after each use, and is in clean condition. It has been cleaned and disinfected again. It has been used 6 times. My dog coughed for the first week after surgery, but after that, we were able to manage with medication alone, so the usage was limited. It is still in good condition, and I hope someone else can use it. ※ Although it is in good condition, it has been used a few times, so please refrain from purchasing if you are concerned about minor details. ※ The box it will be shipped in (the original cardboard box) is slightly torn, but I will pack it carefully, so thank you for your understanding.
